CONDENSER.

Original application iled January 3, 1918, Serial No. 210,146. Divided and this application filed January To all whom t may concern:

Be it lrnown that I, FREDERICK L, MC- GAHAN, a citizen of the United States, re- Siding at the city of Los Angeles, in the county of Los Angeles and State of California, have invented certain new and use ful Improvements in Condensers, of which the following is a specification.

This application is a division from the application of the same inventor for patent for locomotive filed January 3, 1918, serial 210,146, which became Patent 1,292,899, January 19, 1919, and relates more particularly to the condenser for transforming the steam utilized in driving the turbine described in the said application.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur.

Figure 1 is a fragmentary side elevation of the rear end of a locomotive, with portions broken away showing the location and arrangement of the condenser relative to the other parts of the locomotive;

Figure 2 is an end elevation of the condenser showing the same in situ in a locomotive;

Fig. 3 is a diagrammatic plan view showing the turbine, condenser, reservoir, pump, and their connections, and the relation of each. The steam is admitted to the turbine 1 through pipes 1u.

The exhaust from the turbine 1, is into the steam condenser and water cooler 2, the said exhaust passing through pipes 10 thereinto. The condenser 2 is formed of a plurality of square pipes 3, arranged as shown, which, by reason of their form and arrangement, and particularly because of the serpentine course that the steam is obliged to pursue therethrough, as indicated by the arrows in Figure 1, cause condensation of the steam and its cooling because of the large area of pipe through which the steam passes before it reaches the exit 15 to the train line pipe, and also becausevof the draft that flows along the pipes 3 when the locomotive 1s in motion, which draft is enhanced by the hood 6 that incloses the said pipes 3 eX- cept at their ends.

The water formed by the condensation of Serial 110,271,718.

steam iiows back through the pipes 3 and through the outlet 1b through the pipes 4 to pipe 4, thence to the filter 5 where it is puricd, this filter or purifier 5,v consisting of three compartments, constructed of any suitable material.

The water or condensation is transferred by any suitable means through the filter 5 outward through the pipe 11 to the water reservoir 12, from which it is pumped by pumps 14 as distilled water to a boiler through pipe 14a. The pump may be actuated by walking-crane 16 operated by cam 17 on the aXle or shaft 18. l

It will be understood that both steam condenser 2 and water reservoir 12 may be located at any suitable place on the locomotive and may be supported thereon in any suitable manner.

`When the steam as heretofore described, has operated the locomotive and has passed through the condensers 2 after having been made dry by its humidity and condensation being there taken out, it passes through pipe 15 to circulate through the coaches of aA train for heating and other purposes, and after serving its purpose returns through the pipe 15a which joins with the pipe 4 and thereby flows to the filter 5.

Having thus described this invention, I hereby reserve the beneiit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein witlmut departing from the spirit of this invention or the scope of the following claim.

The combination in a locomotive of a source of exhaust steam and a condenser, the said condenser comprising a serpentine coil of square pipes spaced apart, a hood y open at both ends surrounding said coil so as to direct the current of air caused by the motion of the locomotive against said pipes, a filter, means for leading the condensed steam from the condenser to the filter, and means for conveying the water from the filter to the boiler of the locomotive.

In testimony whereof I hereunto affix my signature.
